update a building's ArchiCad 27 files

My organization is in need of an experienced professional to update our building's ArchiCad 27 files. We need minor edits or corrections that will require special attention to specific areas of the building. We understand that this may be a time-consuming task, so we are flexible with our deadline. Ideally, we would like this project completed as soon as possible, but we understand that quality work is dependent on taking the necessary time. We are confident that the right person can work within an appropriate timeline while upholding a high level of quality.
